Osmosis

Although it's hard to see, those are little pieces of sea salt that I had piled in a plate filled with water and osmosis occured in the plate as the water was absorbed from one side of the plate to the portion with the salt found in it.

A form of Passive Transport, osmosis is the process of diffusion of water across a selectively permeable membrane in which the water follows the direction of a higher concentration of solute.
